Coaches coach better.
Athletes train smarter.

Performify is an AI coaching platform for coaches and the athletes they train. Coaches get an AI that thinks like they do, athletes get programming that adapts in real time, allowing coaches to grow their roster without burning out while every athlete still gets a program built just for them.

Drop an exercise and Thor suggests the prescription, a progression or regression that fits your program, methodology, and the athlete, drawing on all known context. You confirm it or change it.

I know exactly what every athlete needs. The problem isn't knowing. It's having the time to deliver it, for all of them, and adjust when their workout doesn't go as planned.
Every coach, eventually.

Coaches know what each athlete needs. The bottleneck has never been knowledge, it's the hours it takes to write individual programs and rewrite them when a session goes sideways. Spreadsheet-era software didn't fix that, and AI apps just cut the coach out. The research is clear on what actually moves the needle.

88% vs 52%
Working with a coach, 88% of athletes stayed the course. On their own, barely half did, and they gained far less strength.
0 to 52%
The same program produced anywhere from no measurable gain to a 52% strength increase, athlete to athlete. Cookie-cutter programs leave real progress on the table.
Backed by peer-reviewed research.

AI built to amplify coaches. Never replace them.

Meet Thor

Thor is the AI orchestrator at the core of Performify. One per coach, shaped by their decisions. Thor learns how each coach thinks and gets sharper with every program written and every adjustment made.

The Whiteboard

Build programs on a card-based canvas. Stage exercises, drop them across a calendar, and let Thor suggest prescriptions trained on your methodology and the evidence base. You stay in the driver's seat for every decision.

Tempering

Write one program, then let it personalize for every athlete. Before each session, Thor adjusts for static context: history, goals, equipment, the things that stay fairly predictable. At the session check-in, it adjusts again for dynamic context: sleep, nutrition, readiness, whatever has changed that day from any prior known context. The coach's intent stays the anchor.

Real-Time Adjustments

Knee acting up mid-session? Rack taken? The athlete tells Thor. Thor suggests options inside the coach's guardrails. The athlete decides. The session keeps moving and the coach is kept in the loop.

One program. Personalized for every athlete.

Write one program. Send it to your whole roster. Through Tempering, Thor reshapes it for each athlete in passes: first on stable context before the session, then on the newest context at check-in, then continually through the workout, so the moment an athlete requests a mid-session change, Thor already has everything it needs to suggest the best one. Every athlete ends up with a program built around them. Your program intent stays the anchor.

Before the session
Stable context

Thor shapes the program around what stays steady or changes predictably: training history, goals, injury flags, equipment access, and more. The athlete starts with a version already built for them.

At check-in
Fresh context

Right before training, Thor folds in the latest: sleep, nutrition, stress, readiness, time available. The session updates to meet the athlete where they are that day.

During the session
Live context

Thor keeps tempering as the workout unfolds, so the moment an athlete requests a change, it already has everything it needs to suggest the best one. The coach's intent stays the anchor throughout.

See how programming actually works in Performify

Drag an exercise onto the calendar and Thor drafts a prescription built for that athlete, their current status, the training block, your methodology and habits, and where it falls in the week. It is the same builder coaches use to turn a blank week into a finished block in minutes, weighing the kind of context other tools never even capture.

Drag an exercise into any day and Thor fills in a prescription. Double-click a card to set the prescription yourself. Drag a day or week onto another to copy it across the block. Star an exercise to pin it to favorites. Trash icons clear a card, day, or week.

In the live product, every suggestion is shaped by your methodology, an athlete's habits and training history, who they are as an individual, and the current body of peer-reviewed sport science, brought together into a single judgment call.

Get in early. Shape everything.

This is an open beta testing phase, no polished product, no promises of perfection. We're looking for coaches who work with multiple clients or groups and aren't afraid of rough edges. Your feedback is what builds this into something great.
